Title: Mesa type semiconductor
Inventor: IITAKA YUKIO
IPC: H01L29/73
Filed: 1983-10-14
Abstract: PURPOSE:To enable the realization of high withstand voltage by preventing the reduction of the thickness of a depletion layer in the surface of a mesa groove by a method wherein the formed depth of an impurity layer of the reverse type to that of a substrate is made small from the neighborhood of the mesa groove to the groove. CONSTITUTION:The angle of intersection theta between a P-N junction plane 6 and the mesa groove 4 becomes an acute angle by shallow formation of a P type diffused layer 2 from the neighborhood of the groove to the groove not by formation all to a uniform thickness. When the angle theta becomes an acute angle in such a manner, the thickness of the depletion layer 5 of the surface of the groove does not reduce even in the case of the upward bending of the bottom corner of the depletion layer; therefore the strength of an electric field in the surface of the groove is not reinforced, and so the withstand voltage improves. In order to make the P type diffused layer shallow from the neighborhood of the mesa groove to the groove, an N type impurity having a thinner concentration than the surface one of the P type impurity is diffused to the groove.
